My question is have you backed on kickstarter?

'nuff said.
Did you pledge because, for some, you are really interested in and want such a game/film/item to come out or simply because you believe in and want to help out the creator?
Almost every times, it's been because I want the thing in question. Knock-knock would be a case of simply believeing in the creator (Ice-pick Lodge, the people behind the Void and Pathologic; it's also worth noting that I signed up for the "blind bargain" pledge level for that one -- curiosity decided to be a ***** that day).
How much did you pledge?
Depending on the project, between $5 (most of the video games have been between $5 and $15, typically the level for a digital copy if there weren't any particularly awesome KS exclusives) and $2500.
Was it a good experience?
That depends entirely on the project. In some cases it was, even in some cases with wildly late projects it has been (for example, the Serpent's Tongue people know how to treat people when you have a very lot of their money collectively and are running increasingly behind on what you've promised them for it -- frequent demonstrations of what you are doing, why it's taking so long, and that it will be worth it in terms of quality in the end). Others have produced more or less exactly what they intended to, in the expected quality, not too late, and have been more than friendly in resolving issues.
Bad experience?
Some of those too. Talk to the Kanzume Goddess backers for an example -- it's an English translation of an existing Japanese card game. This shouldn't be that complicated, but it ended up very late, they lied about shipping more than once, they botched even what they claimed was already shipped, ran out of something that was supposed to be a KS exclusive (and offered to refund $5 of the pledges or exchange for a different KS exclusive that was frequently being damaged in shipping), and to top it off you could by the game from a third party distributor, for cheaper than pledge price, get it with the originally KS exclusive pins they ran out of, and have it before they shipped many of the backer's copies (they were also selling it at PAX East 2013, my copy shipped in late April, despite that everything was supposed to ship before PAX, they then claimed it had shipped by 4/10, then on 4/18 that a certain pledge level had failed to ship [which I wasn't at], and took me pestering them for tracking info for nearly two weeks before mine shipped). That requires a special kind of terrible.
Again, it literally comes down to the individual project. Kanzume Goddess was a disaster in a league more or less of it's own. So is Code Hero (which may or may not ever be completed).
Most of the projects I've backed I would say have gone average to good, but typically late by several months. Everyone is just plain too optimistic in their estimates.
Did you get a sense of really being involved in the project?
Like every other thing I've posted, it depends wildly on the project. Serpent's Tongue has been deep on backer involvement (ranging from playtest feedback to actually encouraging player submitted card and art designs), some of the RPG books have used backers as their main playtest groups, other projects not so much.
Many of the pledge bonuses are exclusive forum access, voting rights on certain decisions, first looks and so on.
Did you get a sense of being important?
Being *important*? Not so much, most of the time.
Did the bonuses increase your donation or did simply believing in the project dictate whatever you gave?
Depends on the project, how enticing the bonuses were, and how much extra they cost. Nice exclusive goodies for relatively cheap FTW. I kinda went big on Zpocalypse, Zombicide, Serpent's Tongue, and Dwarven Froge Game Tiles, for example -- or at least bigger than I otherwise might have.
Would you pledge again?
I keep saying "no", but then...97 projects. You can guess what a more realistic answer might be.
